Is the scaup diving duck population declining?

Although the lesser scaup has the largest population of any species of diving duck in North America, their population has been steadily declining since the mid-1980s, and reached an all-time low in the early 21st century.

How do small birds survive winter?

Still, many small birds do cope successfully with winter — a feat they accomplish through physical, physiological, and behavioral mechanisms. Their fundamental challenge: to maintain body temperature by increasing the production, and reducing the loss, of body heat. Calorie-rich foods, like seeds, allow birds to produce more body heat.

Where do birds sleep at night in December?

As December days shorten, you may wonder where birds, including this Steller’s Jay and others, spend the long, cold nights. It might surprise you to learn that they are not snuggled into cozy nests.

What is a New Zealand scaup duck?

New Zealand scaup are quite unlike any other resident duck species. Dark and squat with a rounded profile, they often occur in large flocks, floating with cork-like buoyancy. Scaup are diving ducks and spend a lot of time underwater, where they can travel considerable distances. Both sexes are dark-plumaged, but are easily distinguished.

What affects nesting success and Duckling survival?

For canvasbacks and redheads, nesting success and duckling survival, affected mainly by annual variation in water conditions, and year-round survival of adult females are the most important factors determining year-to-year changes in populations. For scaup and ring-necked ducks, the interplay of these factors is less well understood.

What kind of bird can dive?

Lots of birds dive for a living, including loons, grebes, and many seabirds. Among the ducks in North America , three distinct groups, or tribes, of species are considered “divers.” The ruddy duck represents a mostly tropical tribe known as the stifftails.

Relationships between common ravens are often quarrelsome, yet they demonstrate considerable devotion to their families.
